SAMANTHA TAN Clinches GTDX Bronze Cup at Road Atlanta IMSA Championship Weekend

October 7, 2025

GRRL! SUMMARY:

SAMANTHA TAN (#38 ST Racing BMW M4 GT3) has mathematically clinched the GTDX Bronze Cup championship with Vincent Barletta’s absence from the field at Road Atlanta. While Adam Adelson can wrap up the overall GTDX title just by starting Thursday’s race, TAN’s Bronze Cup victory shows the depth of talent emerging in this inaugural championship category.
The Road Atlanta weekend serves as the championship finale for three major IMSA support series, with title fights heating up across multiple classes. From the Michelin Pilot Challenge’s nail-biting GS and TCR battles to MX-5 Cup’s $250,000 prize fight, we’re seeing competitive racing where every position matters and championships hang in the balance heading into the final races.
While most series are crowning champions this weekend, the racing quality remains fierce with spoiler potential everywhere. Even locked-in champions like Valentino Catalano in LMP3 and the various cup winners still have pride and momentum to race for, ensuring that every session will deliver the competitive intensity that makes these support series essential viewing alongside the main Petit Le Mans event.
